An object of the present invention relates to provision of a terphenylene derivative having excellent oxidation resistance and capable of forming a semiconductor active phase by a coating process and an oxidation-resistant organic semiconductor material using the same, as well as an organic thin film.
The invention relates to production of a terphenylene derivative represented by the formula (1) by tetralithiating a tetrahaloterphenyl derivative with a lithiating agent and subsequently treating the resulting compound with a copper compound:
